JACOB CLOOS, OF MILVAUKEE, WISCONSIN, ASSIGNOR TO THE CLOOS ELECTRICAL ENGINEERING COMPANY, OF SAME PLACE.

SWITCHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 623,118, dated April 11, 1899. Application filed February 7, 1898. Serial No. 669,294. (No model.)

T0 all whom, it 77mg/ concern,.-

Beit known that I, JACOB CLOOS, a citizen of the United States, residing at Milwaukee,

in the county of Milwaukee and State of Vis-` cousin, have invented a certain new and useful Improvement in Switching Apparatus, (Case No. 2,) of which the following is a full, clear, concise, and exact description.

My invention relates to switching apparatus for controlling the distributionof electricity, andA more particularly currents of high potential, and has for its object, iirst, the provision of an improved form of switching apparatus wherein the switch parts are thoroughly protected and made weather-proof; second, the construction of a switch whereby the circuit changes are effected in a predetermined order in a manner to avoid certain objections vheretofore present in switching mechanism; third, the provision of a switch wherein plugs form circuit-changing parts which are simultaneously operated by lever mechanism, and, fourth, the simplification and improvement of the stationary portions of the switching mechanism. l

My invention consists in apparatus designed to accomplish the above objects, and, generally speaking, in its preferred form may be described asl consisting of an oscillating actuatinglever with plugs suspended thereon and 'a base-plate supporting at its upper and lowerportions thimbles which are adapted to be engaged by the plugs or which in part are disengaged from the plugs in eiecting the required circuit changes. This mechan box, in which oil is provided to immerse the switch parts, the oscillating lever being preferably connected with a reciprocating -rod extending through a stuffing-box to the ex tcrior, the exterior portion of the reciprocat` ing rod being provided with a handle for operating the switching apparatus.

I will explain my invention more particularly by reference to the accompanying drawings, which illustrate the preferred embodinient thereof.

In the drawings, Figure l is a plan view of the switching apparatus in place .within a junction-box, a circuit to which this apparatus is suited being indicated by dotted lines.

Fig. 2 is a sectional elevation on line 2 2 of Fig. l. Fig. 3 is a perspective view of a pair of thimbles entering into the construction of the switching apparatus. Fig. 4 is a diagrammatic view showing the circuit-changin g portions of the apparatus as associated with a working circuit.

Like letters indicate like parts throughout the different views.

I will iirst describe-the mechanical construction of my improved switching apparatus and will then state in what manner it is employed. The supports for. the thimbles q q q2 Q3 and the thimbles r r r2 r3 consist, preferably, of the insulating-base s, anchored to the box, the upper portion of which base forms the support for the thimbles q q' q2 Q3, while the lower portion thereof forms a support for the thimbles o" 7"' T213. By providing the supports for the thimbles in a single piece the alinement ot' opposed thimbles is absolutely xed, so that the plugs are accurately guided into engagement with alined thimbles. upper thimbles are provided with suitable stems adapted for connection with the circuit conductors. The thimbles r and fr are electrically connected. The thimbles r2 and 'r3 are connected, respectively, with thimbles g' q2. The plugs t' t2 t3 are pivotallymounted upon the ends of a centrally-pivoted oscillating lever a, the plugs being insulated from said leverA Slots are provided in the lever to permit the pivot-pins uniting the plugs therewith to move longitudinally with relation to the lever u as the lever is oscillated. A central extension of the lever u is connected with the reciprocating rod c, extending through a stuffing-box n in a wallvof the junction-box w. 1

A packing w is preferably interposed between the cover 102 and the top of the junction-box. The plugs are preferably provided withlongitudinal slits, as illustrated, to permit the same to have a spring-like engagement with the thi mbles. Oil, preferably kerosene, is provided within the junction-box, in which the switch parts are immersed, as shown in Fig. 2.

The system of distribution to which the switch shown is especially adapted is illustrated in Fig. 1i.

The

IOO

The feeders extending from the generator .r are connected with the contact portions or thimbles q' q2 and fr? The loop-circuit y] has its terminals connect ed with the thimbles or contact portions (l The lhimbles and plugs are preferably so relatively disposed that the plugs upon either end of the oscillating lever ,u will connect the alined thimbles associated therewith before the plugs upon the other end of the switch-lever are moved sufficiently to disconnect the thim bles in engagement therewith.

By mounting the circuit switch-plugs upon a switch-lever the changes in the circuit conditions are effected in a uniform and predeterm ined manner. Other flexible connection with the switch-lever than a pivotal connection may be employed.

It is obvious that departures may be made from the preferred embodimentof the invention herein shown and particularly described, and I do not therefore desire to be limited to the precise construction shown; but,

Having thus described my invention, what I claim as new, and desire to secure by Lei ters Patent, is

l. In a switch, the combination with apivotally-mounted switch-lever, of plugs '15 t iiexibly connected with said lever upon one side ofthe pivot, plugs i? t3 Ilexibly connected with said lever upon the other side of its pivot, contact-thimbles q q2, lr2 r3 normally connected with the feeders,electrically-connected thimbles fr fr alined respectively with thimbles @(12, and thimbles q g3 forming terminals ol a loop or distribution-circuit alined re spectively with thimbles r2 r3, the plugs upon the switch-lever being adapted to connect alincd thimbles, substantially as described.

In witness whereof I hereunto subscribe my name this 31st day of January, A. D. 1898.
